摘  要：
为了探索西瓜无公害防病壮苗技术,以常规种子在瓜类连作土上播种为带菌土对照(CK1),以土壤高温消毒为无病菌土对照(CK2),比较了专用种衣剂包衣和3种放线菌剂处理对西瓜防病壮苗的效果。结果表明,CK1西瓜苗期土传病害严重,发病率高达90%;CK2发病率仅为13.3%,防病效果达85.2%;应用种衣剂包衣西瓜种子可以有效防治病害,其发病率为25.6%,防病效果为71.6%;3种放线菌剂A、B、C均有一定的防病促生效果,防病效果分别达16.2%,17.0%和13.3%。综合分析各项指标认为,放线菌剂A处理的西瓜幼苗长势较好,植株健壮,壮苗指数高,叶绿素含量高,根系活力强;种衣剂包衣也是防病壮苗有效而简易实用的方法。

摘  要：
To investigate the safe technology of disease control and strong seedling nursering in watermelon,the effects of seed coating with a self-developed special seed coat agent and soil treatment with three kinds of actinomycete agents on disease control and seedling growth of watermelon were compared by taking normal seed sowing in the cucurbits crop successive growing soil as the control(CK1) of soil with pathogen and the high dry temperature sterilized soil as the pathogen free soil(CK2) in this experiment.The results show that the soilborne disease is very serious and the incidence of the disease is as high as 90% for CK1;the incidence of disease for CK2 is only 13.3% and the disease control effect is 85.2%.To coat watermelon seeds with the seed coat agent can control the disease effectively,the incidence of the disease is only 25.6%,and the disease control effect is 71.6%.Soil treatment with actinomcete agent A,B,or C all has some effect on disease control and growth promotion,and the disease control effect is 16.2%,17.0% and 13.3%,respectively.Based on all indexes,seedlings growth in the soil treated with actinomycete A is stronger and higher in seedling index,chlorophyll content and root vigor.Coating seeds with seed coating agent is also an effective,simple and practical method of watermelon disease control and seedling strengthening.
